A vibration damper for a motor vehicle is taught, which vibration damper has a cylinder tube in which a piston rod which is centered by a piston rod guide can move axially. A container tube encloses the cylinder tube, and the container tube is made of a material which has a significantly higher coefficient of thermal expansion than the material of the cylinder tube. Aluminum is an example if the container tube material. A compensation device compensates for the length difference between the cylinder tube and the container tube at temperatures below and above the temperature at which the vibration damper is manufactured. The container tube is characterized by the fact that preferably at least two expansion beads are formed in the wall of the container tube. The expansion beads compensate for thermal changes in length of the container tube and hold the cylinder tube under a bias with respect to the container tube over the entire range of operating temperatures.

Shock absorbing strut with an aluminum container for a motor vehicle

Fastening device on the outer tube of a shock absorber, comprising a receptacle for the connection to a vehicle axle and, optionally or in combination, additional mountings for a roll stabilizer and for brake hoses, whereby the connection and the additional mountings are at a distance from one another, characterized by the fact that the receptacle and the mountings are components of a one-piece fastening device, whereby the distance between the receptacle and the additional mountings is bridged by a connecting web.
